Análise De Falha E Do Projeto Construtivo De Um Vaso De Pressão

Abstract: Neste artigo foi feita análise da falha e do projeto construtivo de um vaso de pressão germinado, que sofreu uma trinca transversal na região do anel de reforço e solda de interligação da parede horizontal do vaso com a vertical. Primeiramente foi feito ensaio não destrutivo por líquido penetrante para revelar da trinca e o ensaio de ultrassom para medição de espessura da parede do vaso. Para análise dos materiais, inicialmente foram retiradas amostras dos cilindros vertical e horizonal distantes da solda a fi… Show more

“…Considering their location, they were classified into three types: located in the grain boundaries (type 1), aligned along the ferrite (type 2) and dispersed in ferrite grains (type 3) and non-metallic inclusions distributed heterogeneously in the microstructure.Figure 4shows an illustration of the microstructure with the morphologies of the types of ferrite found in this condition and the classification of the precipitates. This microstructure was found to be similar to microalloyed steels and low cabon steel welded joints previously reported byFaria et al (2019);Zhu et al (2019), Hu et al (2019.…”
